Be it known that l, GoTTFRIED S'rUrARQa citizen ofthe UnitedStates, residing at Chi- "ago, in the county of Cook and State of -Illinois,ha\'e invented certain new and useful Improvements fin Electric Permuta-tion?- -Lock Switches, of which thetollowingis a specification.

My invention rela-tes lto improvements in velectric permutation lock' switches.

` One of. the objects of my'invention isgto` I provide `an electric-switch that` can be oper- '..ated lonly after certain instrumentalities rin ing of a. bell, thelightingof a lamp, 1or or any other'alarm signal, may be ers-f tablished oit-instigated in the event that a i false step be made 'in the operation which is' have( been moved yin predetermined vorder as in a. combination lock.

Another object of :ny-invention is to provide a means whereby an alarm, such as the bot ' a' condition precedent to the moving of the switch'member's to closean objective electric Other" and further objects of myufinventionvvill become readily apparent to persons skilled in the art from a consideration 'of they following descri'ption'vvheny taken in conjunctiony with the drawings, wherein- Figure 1 is a plan vieu7 of the device; Fig.

laterally projecting stud 48, upon which is mounted a cross-shaped circuit-closing mem- V.ber 49. Tliisniember is provided with four radiallyY disposed metallic arms 50, 51, 52,

and 53, tliatraree-.electrically connected to-Y gether and are in electricalicontactwith the The cross-shaped part' 149 is curved and is preferably made ofliard.- rubber, or other similar insulatingmaterial.v

A brush' 54. makes resilient contact with the sleeve 46 and is connected with the binding arms 50 to 53 inf'lusive. or any one thereof,

and is connected with the binding-screw 58 irefhich is secured in the bottomwall 1l of the casing, so that when 'any one of the arms 50 to 53 inclusive is brought into contact with he part 57a circuit-will thereby be closed.

The Aupper disk 21 bears a seriesief uply projecting teeth 59, the function and ien. of which will be hereinafter; dei

thus completed between the disk 21 by virtue of'contact ofthe arm 53 therewith, theu` circuit will be closed and completed from the battery B over the wire 63 to the alarm bell 64 and over the wire 65 tothe terminal- Gl, througlithel disk Zito the contactarin 53, and thence to the terminal 55, and 4over .the wire 66 tothe opposite terminal of battei-y B,t-hus ringing 'the 'alarm bell 4'64 or lightinga lamp which may be lacedI in circiifi'tinlieu thereof, or instigatnig any 'other convenientrsignaling means, at a remote point, is may bailesiiled, and thereby indicating thatthere is someiiiiauthorized per-l son -tan'ipeiing with theswitclrlockm The signal 64 maybe established in the manner described, without the knowledge of the )erson who i'satteinpting to operate the loc t. i

After the rod 38 has been depressed in the manner described, and contact has been established.between any one of the arms, as the arm 53, and the member, 5i, without establishing the alarm circuit. towhich Jrefer# however', that anyone of a plurality ofy cir-4 cuits be energized, any yone of which may be' established after the contact .has been made between the arm53 and the member 57, I -pi-ovide'a supplementary switch which may .be Ilocated inside o fthe casing 10, as shown,

or it may be located'at some point remote from the casing, as desired. The switch consists of the rod 6'7, provided with a turn knob- (38 having an index pointer-'69. To the lower fendof the rod67 is connectedI a switch 'arm 70 which is adapted to make-contactwith the stationary switch niemberl and any'l one v of the coacting stationary members 72,y 73, or 74, as desi-red, upon turninfvf 'of the 533, or other such arm, makes contact with' knob 68, Coperat-i-ng indications .2', 73', ,tndv74 are made-upon the upper surface of the casing so that, in conjunction with the pointer 69, the switch leveror. arm 70 may be moved-so as lto close any one of the cir- 73, `the circuit will be"t "losedv through the electric lamps' 76; and likewise, when the arm'70 makes electrical. connection with thc4 contact the circuit will be closed through an electric lockv77 or the like. Thus. any one of the circuits may be energizcdandmay reroessa lo longer in the path ot' the reciprocatlwf'fcross' lil in order that the combination .or be shown on the op of the l'casing the information .of any unauthorixed Therefore', Wheniit; is desired to ection between the arm 52:3 and the M, the rod 438 lis lifted bodily and iatiag portion 4990i the cross., coinin contact .vith the under surface .of the y willmause -the cross part to rotate, i which time the arm 520i the cross ineinvvill brought into position nonY occul-snapagainst the trailing side of the member and prevent the cross from being` operated inthey opposite direction. Thus, each reciprocation of the rod 38, the cross 'xviii turn onefourth of a revolution, prod that slots 35 and 60 are not in the path the' cross',as hertofore described.

'the member 5? without danger of ringing the alarm belln slot 60 of disk :22 may be varied or changed and thus the combination may be changed,

by removing the nuts 32 from the rod l.3, permitting the sleeve 24 and the'disk 28 to be rotated so that the slots 35 and d()` the 'arm 53 and the spring clip-5G` prevent the disk 21 rom'turninglaeosivitfhj but inasmuch as there is a The relation between the dial 151 and the oisk be rotated to anv desired posi-V another position with reference to disk 2'2 while the disk 2;) remains stationary, thus vchanging the relation between the dial l5 and the notch in disk '22 to suitV any conditions that may be desired. Aftevthis operation the sleeve Q-l isiaised until the pin 3l engages another notch in the disk 2S -when the nuts 32 may be tightened inyplace on the rod i3.

.l have shown a nuinberof teethV 59 on the upper surface of the disk 2l. The object ot these 'teeth is to prevent a person from depressing the rod and rotating the knoh ll for the'purpose ot' finding the 'slot in the event that the alarm circuit should be broken. When the rod .'Bbis depressed, so that any one of' the conducting arms 50 to inclusive makes contact with the surface of the disk, the teeth 59 will prevent rotation of the disk. This is a precaution, how-V ever, that is not necessary when the alarm circuit isv in order.
